We also don't know about how milk transports around the country. I do know someone who purchases for a grocery chain and I reached out and she basically just said it's all algorithmically determined now and the milk in your store might come from your state or across the country at any given moment.
We simply don't have enough info to make firm conclusions, and that's a choice that's been made on purpose.
